A simple and efficient one-pot, three-component method has been developed for the synthesis of α-aminonitriles. This Streckerreaction is applicable for aldehydes and ketones with aliphatic or aromatic amines and trimethylsilyl cyanide in the presence of a palladium Lewis acid catalyst in dichloromethane solvent at room temperature.

Aryl imines formed from aldehydes and amines undergo smoothly in situ nucleophilic addition with trimethylsilyl cyanide (TMSCN) in the presence of catalytic amount of hydrated rhodium(III) iodide to afford the corresponding α-aminonitriles in excellent yield. The low catalytic loading (2 mol %), mild experimental conditions, and short reaction time (mostly within 13 min) represent the key features
